You might be looking to install, say, the GNOME Desktop Environment in Fedora 22 (say you installed a spin), so you might check out the available package groups through dnf:
$ sudo dnf group list Last metadata expiration check performed 0:07:56 ago on Tue Oct 6 22:01:54 2015. Available environment groups: Minimal Install Fedora Server Fedora Workstation Fedora Cloud Server KDE Plasma Workspaces Xfce Desktop LXDE Desktop LXQt Desktop Cinnamon Desktop MATE Desktop Sugar Desktop Environment Development and Creative Workstation Web Server Infrastructure Server Basic Desktop Available groups: 3D Printing Administration Tools Audio Production Authoring and Publishing Books and Guides C Development Tools and Libraries Cloud Infrastructure Cloud Management Tools Container Management D Development Tools and Libraries Design Suite Development Tools Domain Membership Fedora Eclipse Editors Educational Software Electronic Lab Engineering and Scientific FreeIPA Server Games and Entertainment Headless Management LibreOffice MATE Applications MATE Compiz Medical Applications Milkymist Network Servers Office/Productivity Robotics RPM Development Tools Security Lab Sound and Video System Tools Text-based Internet Window Managers
Unfortunately, you won’t find an obvious group for your needs. And yet:

Why doesn’t the GNOME group show up in our listing?
Well, in what must be an attempt to better the user experience, it seems Fedora’s repositories a few totally awesome hidden groups:

The “-v” option causes the output to include the parenthetical references to the groups’ group IDs (which are also candidates for the case-insensitive comparison described below, and that’s why our reference to the group ‘gnome-desktop’ worked with the string ‘gnome’).
But man! That’s crazy! Why does that even work!? Shouldn’t it just tell us there aren’t any groups with “hidden” in their names? And look at all this awesome stuff! Tons of language support (which might’ve solved my Chinese IME in KDE woes I posted about a while back – gotta test that one), tons of development tools..
It appears that “hidden” is a super secret <group-spec> which defies all man page explanation:
SPECIFYING GROUPS <group-spec> allows one to select (environment) groups a particular operation should work on. It is a case insensitive string (supporting globbing characters) that is matched against a group's ID, canonical name and name translated into the current LC_MESSAGES locale (if possible).
From reading that, one might expect the ‘dnf group list hidden’ command to display any packages whose ID, canonical name, or translated name might be matched case-insensitively against the string ‘hidden’. That is, after all, what the explanation tells us will happen.
Unfortunately, I don’t know why this works. I know support for hidden packages was included as a feature of yum, and its most obvious use is as a convenience for end users (since I’m sure many of these groups are subgroups of other Fedora groups). Unfortunately, it seems the productization of Fedora has led to a little strangeness ’round these parts:
$ sudo dnf group info workstation-product-environment Last metadata expiration check performed 0:46:35 ago on Tue Oct 6 22:01:54 2015. Environment Group: Fedora Workstation Description: Fedora Workstation is a user friendly desktop system for laptops and PCs. Mandatory Groups: Common NetworkManager Submodules Core Fedora Workstation product core Fonts Guest Desktop Agents Hardware Support LibreOffice Multimedia Printing Support base-x
Everyone knows Fedora Workstation comes with the GNOME Desktop Environment…so where’s that gnome-desktop group? For what I’m sure are interesting reasons, it appears the “Fedora Workstation product core” group (Group-Id: “workstation-product”) simply contains a bunch of GNOME packages (but not all). It looks like this was done at least in part to avoid using certain packages rolled up into the gnome-desktop group, such as gnome-packagekit (Fedora Workstation favors instead the PackageKit RPM).
So it’s conceivable that the gnome-desktop group was hidden in order to avoid confusing standard users of the Fedora Workstation product since that product already contains GNOME packages through the workstation-product group, and to avoid users accidentally installing packages which conflict with the versions used by the Fedora Workstation product.
But that’s just my guess. An hour or so of Googling turned up no explanation, so if anyone knows the whole story, feel free to chime in.

Great info. Thanks!

Cheers for this. I”ve referrered to this list often.
